With the rapid development of technology, infrared emitter LED has become an essential component in various applications. This article aims to provide an in-depth introduction to the infrared emitter LED industry, covering its history, technology, applications, market trends, and future prospects.

History of Infrared Emitter LED

The infrared emitter LED, also known as infrared LED, is a semiconductor device that emits infrared light when an electric current passes through it. The concept of infrared emitter LED dates back to the early 20th century. In 1900, British physicist Sir William Crookes discovered that certain materials emit infrared radiation when subjected to electric current. This discovery laid the foundation for the development of infrared emitter LED. In the 1960s, the invention of the first infrared emitter LED by General Electric marked the beginning of the infrared LED industry. Since then, the technology has been continuously improved, and its applications have expanded to various fields. In the 1980s, the infrared emitter LED industry entered a rapid development period, with the emergence of high-brightness infrared emitter LED. Today, infrared emitter LED has become an indispensable part of our lives.

Technology of Infrared Emitter LED

The infrared emitter LED is a semiconductor device, which mainly consists of a p-n junction. When an electric current passes through the p-n junction, electrons and holes recombine, releasing energy in the form of infrared light. The key factors affecting the performance of infrared emitter LED include the material, structure, and drive mode. The material of infrared emitter LED is mainly gallium arsenide (GaAs), gallium phosphide (GaP), and their alloys. Among them, GaAs is the most commonly used material due to its high photoelectric conversion efficiency and long service life. The structure of infrared emitter LED can be divided into two types: surface-emitting and edge-emitting. Surface-emitting infrared emitter LED has a simpler structure and lower cost, while edge-emitting infrared emitter LED has higher light output and better beam quality. The drive mode of infrared emitter LED is mainly divided into DC drive and AC drive. DC drive is simple and easy to implement, but it has poor heat dissipation performance. AC drive can improve the heat dissipation performance of infrared emitter LED, but it requires more complex circuit design.
